2. Gmail alias

This is an optional step which allows you to send from your gmail address under an alias of your custom domain email. That is, from [email protected] it will appear to others as if your email is [email protected]

In mailgun select your domain and go to Manage SMTP credential. Create a SMTP credential for the alias you want. In this case it’s [email protected] Take note of the password as you’ll need it later.

In Gmail go Settings > Accounts and Import > Send mail as. Fill in all the details which are a combination of the SMTP user you just created and the Domain information from mailgun.

That’s it! You can now use this alias to send your emails. Some Apps also allow you to use this alias to send.
